7 I The invention relates to means for supporting the motor frames orcasings of motor car trucks, and particularly to the typein 1 which theframe or casing of an electric motoris swivelled at one end on the wheelaxle to which the motor'is geared, and which is supported at itsopposite end by means .pro-

vided on a transverse member of, the truck a j frame. v

The present'inventionseeks to provide simple and inexpensive means for.securely s supporting theomotor frameupon a transverse member of thetruckzframe, and which is readily adjustable topermit the verticalmovement of the truck frame in opposite directions, withoutnecessitatingthe removal of other parts of the truck. i p

The invention consists in the features'of improvement hereinafter setforth, illustrated in the preferred forms in the accompanying drawings,and more particularly pointed out in the appended claims.

In the drawingsi c 7 Fig. 1 is a view partly in elevation, and partly inlongitudinal section of a motor car truck with the present improvement.applied thereto. v v

Fig, 2 is auview partlyin elevation. and partly in transverse section ofthe central portion of the. car truck, and showing the improved motorsupporting means in elevation.

Fig. 3 is a detail section on the line 3- -3 eeri 2.

I risers a plan view of the transverse member or transom. of the truckon which themotor supporting means is mounted.

5 and 6 are detail'views similar to F 2; illustrating modifications.

Vfhile applicable to other types, the pres Cent improvement is shownapplied to a car truck inwhich means is provided for permitting; alimited vertical swinglngmove- (ment of the truck side frames relativelyto i the transverse connecting member .or transonnto avoid shocks inpassing over irregularities in the track. As shown, the cast metal sideframes of the truck comprise compression and tension members 10v and 11,columns ,12and pedestal aws 13for receiving the car hangers 24ldependthrongh openings tegral with the end journals. Keys 18 fixed invsuitable seats in the columns 12 of the side frame engage slots formedin stiffening ribs 19 on side portions of the end journals 16 of thetransom and. interconnect the transom and side frames in a mannerpermitting the relative swinging movement, to a limited extent, of theside frames. A truck bolster 20, bolster springs 21-and spring plank 22are disposed between the sidewalls 17 of the transom, and the springplank is supported upon cross bars 23 carried by hangers 24- dependinfrom the end portions oi"? th transom side walls. Prel erably, asindicated in 4, the transom side walls are hollow and the 25 therein.

An electric motor mounted on and geared. to one of the wheel QXlGS 26and, if desired each axle may he provided with a motor. As shown themotor frame or casing 27 interposed between the wheel axle and theadjacent side wall 17 of the truck transom and at one'ond is swivelledon the wheel axle, being rmnovahly connected the etc by a suitable axlecap 28. At its opposite end, the motor frame is provided with a nosingwhich comprises upper and lower centrally disposed jaw lugs 29 and 30and the motor frame is also provided at its end with spaced safety lugs31.

A transv s-mpporti: unit is disposed and 30 of the motor nosing ai smounted on the adjacent side wall of the transom cooperate with the endsof the i-znpporting unit to hold the motor "frame in position, thosebrackets being posed spring or springs. A semi-elliptical leai spring 83is shown in Figs. 1. to tinclusire, and the form shown in Fig. 6provided with a: series of spiral springs 34. In

unit, the brackets bein of substantial similar construction for thediil'erent units shown in Figs. 2, 5, and 6. The bracketsare formed ofstout castings and each comprises a base portion 37,:111 outwardlyprojecting.vertical flange 38 and a pair 01 upper and lower lugs 39 andt0, the flanges and lugs being" integral with the base portion. Eachbracket is also provided with upper and lower flanges ll and l2 whichembrace the transom side walls 1.7 and have a slidinglit thereon. Also,as

shown, the upper flange of each bracket and are machined] the adjacentedge portion of the transom side wall are provid d with interlocking;ribs -3 and 44:. To facilitate the lateral slid movement of the bracketson the transon base 87 and the adjacent face of the side wall I areprovided with pads and all e I l engaging surfaces of the bracket andtransom The portions of the transom greater heightthan the relativelycontracted central portion 17, and the supporting brackets can beappliedto this contracted central portion and then moved outwardly to, effectthe interlock ng engagement of the ribs 43 and 4 and the sliding fit ofthe lower flanges 42 of the brackets upon the loweredg'e In theoperative'positions of the brackets, the, supporting unl carried by themotor nosing disposed between the vertical flanges 38 ofthe brackets andthe b. icke't, hig 39 and l0 extend over aml'below the ends thebrackets, the safety lugs on the motor 'frame are disposed above butspaced to a sngl'it extent from the intal portions or lugs -17 on theupper portioi of the braclmts.

By removing the bolts 46, the brackets can beslid further outwardly uponthe side wall of the transom to clear the'ends of the supportingunitsand'the motor frame can then be either raised or lowered from itsnormal position to afi'ordacc'ess thereto for repairs,

ed to or can be readily removed if desired-without disassembling otherparts of the truck. The upper and lower bars or the supporting unitscarried by the motor nosing snugly engage the jaw lugs'29 and 30 of themotornosing and the lugs 39 and tOof thebrackets. To relievethe bracketlugs from pressure and thereby facilitate the lateral adjustment ofthe;brackets to inoperative position, the. up-

per and lower springbars 32 are preferably connected by bolts 48 havingnuts 49 thereon which can be tightened to draw the bars together. Whenthe brackets have been "shifted outwardl gthe nuts can be again loosenedso that the upper and lower bars are again spring-pressed intoengagement with the jaw lugs of the motor nosing. As the-side framesrock in vert cal planes in passing over irregularities in the track, the

wheel'axles rock to a slight extent in transverse vertical plane. Tofacilitate this rocking movement of the wheel axle without 'stramlngthemotor supporting means, the

upper and lower bars 32am .35 of the supporting units carried by themotor nosing are provided with seatingfaces 50 forthe jaw lugs-which areconvekly I curved, as

. shown in Figs. 2', 5, and 6.

The weight of the motor and the load this to its rotation in onedirection is transmitted V 1 through the supporting unit to the lowerside 'vallv 17 1 upon which the brackets slide are'of slightly lugs ofthe brackets, whi'le the load due to the rotation of the motor in theopposite direction'is transmitted to the upper bracket lugs; Springunits, such as sh'own in Figs. ,2 and 6, are required for alternatingcuropposite end, and a br acket carried by thev truck memberhaving-integral upper and lower projecting" lugs adapted to cooperatewith said nosing to supportthe motor frame, said bracket being slidablymountedfforlateral adjustment on the, face of the truck transom topermit. the raising or lowering of the motor frame, substantially asdescribed. 1
